  • a power saving mode of the peripheral device 430 is enabled at step S20, if an external source exists.
  • the output voltage level of the battery 410 is detected, if the external source does not exist, and then it is determined at step S30 whether the output voltage level of the battery 410 is the normal operating voltage of the system.
  • the power saving mode of the peripheral device 430 is enabled, as at step S30, if the output voltage level is normal.
  • step S40 It is then determined at step S40 whether the output voltage level is equal to the first reference voltage VrefLB, when the output voltage level of the battery 410 is not the normal operating voltage of the system.
  • the output voltage level is continuously detected until it drops to the first reference voltage VrefLB.

Thereafter, step S50 is performed and the output level of the battery 410 is detected. It is determined at step S60 whether the output voltage level is equal to the second reference one VrefLLB.
  • the computer system 400 stores current information and data being used into the peripheral device 410 at step S70, if the output voltage level of the battery is equal to the second reference one VrefLLB. On the other hand, the output voltage level of the battery is monitored until it reaches the second reference voltage VrefLLB at step S60, if the output voltage level is not equal to the second reference one VrefLLB. After performing step S70, the computer system stores current information data and turns itself off.
  • the invention resolves the problems mentioned above as follows.
  • the amount of power used by the computer system is relatively higher than that of the battery, if the computer system activates a peripheral device and stores current data when the output voltage level of the battery is the second low battery voltage level. Owing to this, the system power source is cut off, and the computer system is shut down, resulting from the loss of the user's information and data.
  • a portable computer system first activates the peripheral device when the output voltage level is at a first low battery voltage level higher than the second low battery voltage level. Also the portable computer system stores the current state when the output voltage level is at the second low battery voltage level. Therefore, the invention can prevent the steep increase of the amount of power consumed at the second low battery voltage level and the loss of the users' information and data, due to the turning off of the power source before the current state is stored and extend the operating time of the computer system.
